2. A trolley for supporting a load for movement along a'r'langedbeamcomprising a pair of oppositely arranged arms, an inwardly positionedroller journaled upon the upper end of each of said arms and mountedupon the said beam, each of said arms having intermediate its ends apair of aligned oppositely extending outwardly projected taperedhalf-circular threaded portions at right angles to said arms which arecentrally grooved to receive portions of a longitudinally threadedportions constituting'a lug for receiving a nut, a nut on each of thelugs formed by said complemental portions, each nut consisting of a pairof symmetrical separable parts so formed as to inter-lockingly engage toform a unitary self-locking nut when introduced over the cable andthreaded upon said threaded portions, whereby the turning oi the nutsinwardly on the cable for securing the same to said-arms. 3. Atrolleyior transporting a load along a flanged beam comprising a pair ofupright oppositely arranged arms, an inwardly positioned rollerjournaled upon the upper end of each arm and riding upon the'ilanges ofsaid beam, each of said arms having intermediate its ends a pair ofaligned oppositely arranged laterally extending half-circular threadedportions at right angles movable cable, the complemental each other ofsaid complemental tapered porsupported by to said arms upon each sidethereof and having central elongated grooves therein to retaininglyreceive portions of a longitudinally movable cable, a nut on each ofsaid complemental threaded portions, each nut consisting of a pair ofsymmetrical separable parts so formed as to inter-lockingly engage eachother to form a unitary self-locking nut when introduced over the cableand threaded upon said threaded portions.

4. A trolley for transporting a load along a flanged beam comprising apair of rollers positioned upon the flanges of said beam, means saidrollers comprising depending arms for eachroller upon which the latteris journ'aled, means for attaching a portion of a longitudinally movablecable to each arm, including a nut, the arms each having intermediatetheir ends a laterally extending complemental half-circular threadedportion at right angles to said arms, centrally grooved to retain-inglyreceive a cable, and when assembled forming a threaded tapered lug, uponwhich said nut is positioned, each nut consisting of a pair ofsymmetrical separable parts so formed as to interlockingly engage eachotherflto formav unitary self-locking nut when introduced over the cableand threaded upon said lug.
